Annalena on Electricity

For a circuit: a power supply (Battery) and something that
needs the power (lamp) and something to carry the current (Copper wire)

Electrons flow out of the negative side of a battery and
travel along the conducting material, they are attracted to the positive end of
the battery.

Vampire energy:
sends more than 87 billion pounds of heat-trapping carbon dioxide into the
atmosphere each year.

Energy goes to the lights and things that stay on after the
appliance has been turned “off”

Chargers/toasters/washing machines/etc. left in the wall
also expend energy even if there’s no light visible

One of the most common ways to produce electricity is
through the burning of fossil fuels (coal, oil, and natural gas). When fossil fuels are burned, they
release carbon dioxide into the atmosphere, which leads to acid rain and global
warming.

We refer to a lot of things as “energy"= fuels for
cars/production/and electricity!

In the United States, the most common way to make
electricity is by burning coal, which is also the dirtiest fossil fuel that
releases the most carbon dioxide
